20.500.12556/DKUM-59933 Problematika vzdrževanja plinovodnih sistemov Issues at maintanance of gas pipeline systems Podiplomsko delo obravnava problematiko periodičnega nadzora in preizkušanja posameznih sklopov plinovodnega sistema. Določene preizkusne metode je možno izvajati samo na določenih sklopih oz. segmentih plinovodnega sistema. Tako so nekateri deli boljše, nekateri pa slabše nadzorovani oz. periodično pregledani. Analiza je pokazala, da bi bilo treba dopolniti predvsem posebne inštalacije, kot so nadzemni in težje dostopni deli plinskih, razdelilnih in kompresorskih postaj ter plinovodi manjših premerov. Nekateri od teh segmentov niso katodno ščiteni, velikokrat so težje dostopni, dostop je lahko povezan z večjimi stroški, obstoječih metod pa ni možno izvajati ali so rezultati nezanesljivi. V nalogi so nakazane metode, ki jih je potrebno preizkusiti na omenjenih sklopih in oceniti njihovo uspešnost, vsekakor pa je treba spremljati razvoj na področju neporušne defektoskopije in po možnostih preizkusiti in vpeljati nove metode. Posebna pozornost je namenjena analizi in rešitvi problemov pregledovanja plinovodov malega premera. Analiza in odgovori pa odpirajo nova vprašanja. This postgraduate work treats issues at periodical supervision and testing of particular segments of gas pipeline systems. Several test methods can be applied only to particular complexes or segments of gas pipeline systems which leads to deviations in quality of periodical supervision and testing. Analyses proved that special installations such as over-ground and difficult-to-access segments of gas pipelines, distribution and compressor stations, as well as gas pipelines of smaller diameters, need to be improved. Some of them have no cathode protection, some are difficult to access and/or is access to them costly all of which prevents application of present test methods or leads to unreliable results. In this work several methods, that are to be tested and evaluated on the above mentioned segments, are indicated. Constant follow-ups of developments in the field of non-destructive inspection, testing of new methods and, if possible, their introduction is highly recommended. Special focus of this work is on analysis and problem-solving at gas pipelines of small diameters. The analysis and its results open several new questions. plinovodi problematika vzdrževanja pregledovanja in preizkušanje gas pipelines maintenance inspection and testing problems true true false [S.
